New 5150 won't display anything on 1907FP monitor

I've just received and set up my new Dimension 5150 but no picture displays on my 1907FP Monitor.

I've connected the DVI cable to the back of the ATI Radeon 600 video card and the USB cable to a USB port.

The self test function works and so there's nothing wrong with the monitor. I've tried going through the on-line Dell Support, but nothing there helps me.

When I turn the monitor on first, I see the Dell Genesis screen briefly but then blank. Pressing the select input button gives the analog self-test screen. Pressing it again gives "2. Digital" for a moment and then blank again.

The equivalent thing happens if I disconnect the DVI cable and use the VGA cable instead.

I would contact a Dell Technician on-line but I need my Service Tag and unfortunately this is illegible - a couple of the characters are blurred and I gave up after guessing about 30 combinations!

When I turn the PC on, it makes a few very short whirry noises and then stops. The power light is green and solid and there's the numbers 3 and 4 lit up in green.

I was hoping getting a new PC would be straightforward, but I seem to have fallen before the first hurdle! :smileysad:

Your service tag will also appear on your invoice as well as a sticker on the computer. Not sure where you were reading it from. You don't need the tag to contact support. Use Chat or email and contact them asap.
